Yamaha Trumpet Mouthpiece

Great piece

Received timely and just what my son asked for

I was looking for a mouthpiece the same rim as the yamaha 14a4a but with a deeper cup but not as deep as a bach 3c, so I ordered both the yamaha 14c4 and 14b4 and I absolutely adore the b4 it fits my lips just right and I have a wonderful range of flexibility. Can recommend for anyone in the same predicament as me!
